Description

Technical Field

[0001] This invention relates to the technical field of soil sampling, and more particularly to a soil sampling device and method for agricultural information collection. Background Technology

[0002] Soil testing and sampling are crucial technical means for assessing soil environmental quality, understanding soil properties, and promoting sustainable soil management. This technology is based on several key points: soil is a core resource for agricultural production and a vital material foundation for human survival; its quality directly impacts food security and ecological health. Therefore, regular and systematic soil testing is essential. Soil testing aims to understand the degree and trend of soil pollution, as well as the current state of soil environmental quality, thereby providing a scientific basis for soil management and environmental protection. Sampling is a critical step in the soil testing process. Sampling not only affects the accuracy of the test results but also directly influences subsequent analysis, evaluation, and decision-making. To ensure the scientific validity and representativeness of the sampling, a series of strict technical specifications must be followed. First, appropriate monitoring points should be determined based on the monitoring objectives and requirements, combined with the results of on-site investigation. These points should comprehensively cover different types of survey and monitoring unit areas and represent the soil environmental quality status within those areas. During deep soil sample collection, a drill pipe is used to penetrate the soil and extract the soil samples to be tested.

[0003] However, the current sampling drills cannot easily remove the soil from the drill tube after the sampled soil is taken out. The soil surface will generate high friction with the inner wall of the drill tube, which will affect the soil removal. In addition, the sampled soil needs to be broken up with crushing equipment before it can be tested, which will affect the testing efficiency. Furthermore, the inner wall of the drill tube cannot be cleaned in time, making it impossible to carry out subsequent sampling in a timely manner. Summary of the Invention

[0030] Reference Figures 1-5 The first embodiment of the present invention provides a sampling method for a soil sampling device for agricultural information collection, which enables soil fragmentation and convenient soil discharge.

[0031] First, the sampling mechanism 100 is activated to drill into the soil and take soil samples. Next, the discharge mechanism 200 is activated to break up and discharge the sampled soil. This breaking up not only facilitates subsequent testing but also makes it easier to remove the soil. Finally, activating the cleaning mechanism 300 will clean the sampling mechanism 100 and the discharge mechanism 200. Example 2

[0032] Reference Figures 1-4 In the second embodiment of the present invention, a sampling mechanism 100 and a discharge mechanism 200 are provided to realize soil sampling and crushing discharge.

[0033] The sampling mechanism 100 includes a sampling frame 101. A mounting plate 102 is provided at the bottom of the front of the sampling frame 101. A sampling cylinder 103 is movably connected inside the mounting plate 102. A sampling slot 104 is provided on the front side of the bottom of the sampling frame 101. A transmission assembly 105 is fixedly connected to the top of the back of the sampling frame 101.

[0034] The discharge mechanism 200 includes an electric telescopic rod 201. The bottom of the electric telescopic rod 201 is fixedly connected to the top of the sampling frame 101. The bottom of the electric telescopic rod 201 extends through to the front of the sampling frame 101 and is fixedly connected to a transmission plate 202. The bottom of the transmission plate 202 is fixedly connected to an insertion rod 203. Both sides of the insertion rod 203 are movably connected to swing crossbars 204. A movable sleeve 205 is fitted on the outer side of the surface of the swing crossbar 204. A guide block 206 is fixedly connected to the outer side of the movable sleeve 205. A spring 207 is fixedly connected to the inner side of the inner wall of the swing crossbar 204. A threaded guide groove 208 is opened on the inner wall of the sampling cylinder 103. An air jet assembly 209 is fixedly connected to the left side of the inner wall of the movable sleeve 205.

[0035] The transmission assembly 105 includes a hydraulic cylinder 105a. The back of the hydraulic cylinder 105a is fixedly connected to the top of the back of the sampling frame 101. The piston rod of the hydraulic cylinder 105a is fixedly connected to a transmission frame 105b. The front of the transmission frame 105b extends to the front of the sampling frame 101 and is fixedly connected to the back of the mounting plate 102. A motor 105c is fixedly connected to the right side of the bottom of the inner wall of the mounting plate 102. A gear 105d is fixedly connected to the output end of the motor 105c. A gear ring 105e meshes with the left side of the gear 105d. The gear ring 105e is sleeved on the top of the surface of the sampling cylinder 103.

[0036] The jet assembly 209 includes a first piston rod 209a, the outer side of which extends through the interior of the swing crossbar 204 and is slidably connected to the inner wall of the swing crossbar 204. The right side of the first piston rod 209a is fixedly connected to the other end of the spring 207. The outer sides of the top and bottom of the swing crossbar 204 are connected to a first connecting valve 209b. The top of the left side of the swing crossbar 204 is fixedly connected to a second connecting valve 209c. The inner sides of the top and bottom of the movable sleeve 205 are provided with ventilation grooves 209d. The interior of the ventilation grooves 209d and the outer side of the first connecting valves 209b are fixedly connected to filter pads 209e. The inner side of the bottom of the swing crossbar 204 is provided with a limit ring 209f. The inner side of the limit ring 209f is fixedly connected to both sides of the insertion rod 203.

[0037] The top and bottom of the inner wall of the movable sleeve 205 are provided with limiting grooves 209g. The inner wall of the limiting groove 209g is slidably connected to the limiting strip 209h. The inner side of the limiting strip 209h is fixedly connected to the surface of the swing crossbar 204.

[0038] Specifically, when the user needs to take soil samples from the ground, the hydraulic cylinder 105a is activated, causing the sampling cylinder 103 to move downward and extend into the soil to remove the soil sample.

[0039] After the soil sampling is completed, the installation cover can be removed to seal the bottom of the sampling cylinder 103. Then, the electric telescopic rod 201 is started, which drives the swing crossbar 204 through the insertion rod 203. The sampling cylinder 103 is then rotated to break up the soil sample inside. When it is necessary to discharge and collect the broken soil sample, the installation cover is removed, and the motor 105c is started again. The motor 105c drives the sampling cylinder 103 to rotate, thereby discharging the loose soil sample. At the same time, the sliding of the guide block 206 inside the threaded guide groove 208 can also discharge the residual soil sample on the inner wall.

[0040] Furthermore, when the user needs to take soil samples from the ground, firstly, the sampling frame 101 is moved to the sampling location. Then, the user can activate the hydraulic cylinder 105a, which causes the sampling cylinder 103 on the mounting plate 102 to move downward and extend into the soil. At the same time, the user turns on the motor 105c, which then drives the gear 105d to rotate. The rotation of the gear 105d then drives the sampling cylinder 103 to rotate through the gear ring 105e, causing the sampling cylinder 103 to rotate downward and drill into the soil for sampling. Then, the user starts the hydraulic cylinder 105a again, which drives the sampling cylinder 103 to move upward through the mounting plate 102, thereby removing the soil sample from the soil.

[0041] After soil sampling is completed, the mounting cover can be removed to seal the bottom of the sampling cylinder 103. The user can then move the electric telescopic rod 201 downwards, causing it to drive the insertion rod 203 downwards via the transmission plate 202 to drill into the soil sample inside the sampling cylinder 103. This causes the insertion rod 203 to drive the swing crossbar 204 inwards. Next, the motor 105c is started to rotate the sampling cylinder 103 via the gear 105d and gear ring 105e. As the sampling cylinder 103 rotates, the threaded guide groove 208 rotates accordingly. The guide block 206 intermittently engages with the threaded guide groove 208 during its rotation, guiding it along the threaded guide groove. 208 swings upward, and then the guide block 206 drives the swing bar 204 to swing upward. At the same time, the spring 207 pushes the movable sleeve 205 to make the guide block 206 fit more closely to the threaded guide groove 208. When the swing reaches the maximum space, the guide block 206 will disengage from the threaded guide groove 208. Then the swing bar 204 will swing downward to reset. At the same time, the maximum downward space is limited by the limit ring 209f. This cycle can realize the up and down swing of the swing bar 204. The up and down swing of multiple swing bars 204 can break up the soil sample in the sampling tube 103. At the same time, the rotation of the sampling tube 103 causes the soil sample to be squeezed by the swing bar 204, thereby further improving the breaking up of the soil sample.

[0042] When it is necessary to discharge and collect the broken soil sample, first turn off the motor 105c to stop the sampling cylinder 103 from rotating. Then, the user can take the collection box and move it to the bottom of the sampling cylinder 103 and remove the installed cover. Then, turn on the motor 105c again so that the motor 105c drives the sampling cylinder 103 to rotate and discharge the loose soil sample. At the same time, the sliding of the guide block 206 inside the threaded guide groove 208 can also discharge the residual soil sample on the inner wall.

[0043] As the movable sleeve 205 reciprocates, it drives the first piston rod 209a to reciprocate inside the swing crossbar 204, thereby continuously pushing the gas through the first connecting valve 209b, the second connecting valve 209c and the ventilation groove 209d to be discharged and blown onto the soil sample surface. The airflow pushed out can continue to loosen the broken soil sample, thereby improving the breaking effect of the soil sample. When the broken soil sample is discharged, the airflow can also continue to loosen the residual soil sample on the inner wall of the sampling cylinder 103, thereby cleaning the inner wall of the sampling cylinder 103.

[0044] It should be noted that the swing bar 204 is movably connected to the insert rod 203 through a torsion spring bearing seat, and the torsion force of the torsion spring facilitates the reset of the swing bar 204. Example 3

[0045] Reference Figures 1-3 5. In the third embodiment of the present invention, a cleaning mechanism 300 is provided to clean the device.

[0046] The cleaning mechanism 300 includes a water spraying component 301 and a water-saving component 302.

[0047] The water spray assembly 301 includes a piston cylinder 301a. The bottom of the piston cylinder 301a is fixedly connected to both sides of the top of the sampling frame 101. A second piston rod 301b is slidably connected inside the piston cylinder 301a. The bottom of the second piston rod 301b extends through to the front of the sampling frame 101 and is fixedly connected to both sides of the top of the mounting plate 102. Movable grooves 301c are provided on both sides of the top of the mounting plate 102. Mounting pipes 301d are provided on both sides of the bottom of the mounting plate 102. A water spray ring 301e is provided at the bottom of the inner side of the mounting pipe 301d. Several water spray rings 301e are provided and are evenly distributed. A one-way water inlet valve 301h is connected to the rear side of the top of the piston cylinder 301a. The one-way water inlet valve 301h is connected to an external water source. A one-way water outlet valve 301i is connected to the front side of the top of the piston cylinder 301a. The other end of the mounting pipe 301d is connected to the one-way water outlet valve 301i.

[0048] The water-saving component 302 includes a press valve 302a, which is provided in a plurality of equal distances. The outer side of the press valve 302a is connected to the mounting pipe 301d. A water spray ring 301e is sleeved on the surface of the press valve 302a and is connected to the press valve 302a. A pressure relief valve 301f is connected to the right side of the top of the piston cylinder 301a and is connected to an external water source. A double inclined block 301g is fixedly connected to the inner side of the press valve 302a.

[0049] Specifically, the water spray ring 301e is activated to clean the insertion rod 203 and the swing crossbar 204. The sprayed water will also flow into the sampling cylinder 103 to clean the sampling cylinder 103.

[0050] Furthermore, after the soil sample is prepared, the user activates the electric telescopic rod 201 to move the mounting plate 102 upwards and reset it. This causes the mounting plate 102 to move the second piston rod 301b upwards, squeezing the water in the piston cylinder 301a upwards and discharging it through the one-way outlet valve 301i into the mounting pipe 301d. The mounting plate 102 also moves the insertion rod 203 and the swing crossbar 204 upwards, causing the swing crossbar 204 to approach the double inclined block 301g, thereby gradually... When the double inclined block 301g comes into contact with the pressure valve 302a, which moves within the movable groove 301c to avoid being affected by the mounting plate 102, the double inclined block 301g is then pushed outward to press the inner side of the pressure valve 302a, causing the pressure valve 302a to open. At this point, the water spray ring 301e will connect to the mounting pipe 301d through the pressure valve 302a, and then the opened water spray ring 301e will open and spray water onto the insertion rod 203 and the swing crossbar 2. 04 Cleaning is performed. The corresponding water spray ring 301e will only open and spray water when the corresponding double inclined block 301g moves outward, thus achieving the effect of opening layer by layer. When the second piston rod 301b moves upward and the other water spray rings 301e are not opened, the pressure in the piston cylinder 301a will be too high and the pressure relief valve 301f will be opened, so that the excess pressure will drive the excess water back to the external water source for recycling. This avoids the phenomenon that a large number of water spray rings 301e will not be aligned with the insertion rod 203 and the swing crossbar 204 for cleaning when all the water spray rings 301e are opened at the beginning of the movement of the insertion rod 203, resulting in water waste. In addition, the sprayed water will also flow into the sampling cylinder 103 to clean the sampling cylinder 103. When the electric telescopic rod 201 drives the insertion rod 203 to move downward, it will simultaneously drive the second piston rod 301b to generate a suction force in the piston cylinder 301a, thereby drawing water from the external water source into the piston cylinder 301a through the one-way water inlet valve 301h for standby.

[0051] The remaining structure is the same as that in Example 2. Example 4

[0052] Reference Figures 1-5 This is the fourth embodiment of the present invention, which differs from the third embodiment in that: this embodiment provides a soil sampling device and method for agricultural information collection.

[0053] When a user needs to take soil samples from the ground, the user first moves the sampling frame 101 to the sampling location. Then, the user can activate the hydraulic cylinder 105a, which causes the sampling cylinder 103 on the mounting plate 102 to move downward and extend into the soil. At the same time, the user turns on the motor 105c, which then drives the gear 105d to rotate. The rotation of the gear 105d then drives the sampling cylinder 103 to rotate through the gear ring 105e, causing the sampling cylinder 103 to rotate and move downward through the sampling groove 104 to drill into the soil for sampling. Then, the user starts the hydraulic cylinder 105a again, which drives the sampling cylinder 103 to move upward through the mounting plate 102, thereby removing the soil sample from the soil.

[0054] After soil sampling is completed, the mounting cover can be removed to seal the bottom of the sampling cylinder 103. The user can then move the electric telescopic rod 201 downwards, causing it to drive the insertion rod 203 downwards via the transmission plate 202 to drill into the soil sample inside the sampling cylinder 103. This causes the insertion rod 203 to drive the swing crossbar 204 into the sample. Next, the motor 105c is started to rotate the sampling cylinder 103 via the gear 105d and gear ring 105e. As the sampling cylinder 103 rotates, it drives the threaded guide groove 208 to rotate as well. The guide block 206 intermittently engages with the threaded guide groove 208 during its rotation. During this engagement, the guide block 206 swings upwards along the threaded guide groove 208, which in turn drives the swing crossbar 204 to swing upwards. Simultaneously, the pushing force of the spring 207 on the movable sleeve 205 allows the guide block 206 to fit more closely to the threaded guide groove 208. When swinging to the maximum space, the guide block 206 will disengage from the threaded guide groove 208, and then the swing bar 204 will swing downward to reset. At the same time, the maximum downward space is limited by the limiting ring 209f. This cycle can realize the up and down swing of the swing bar 204. The up and down swing of multiple swing bars 204 can break up the soil sample in the sampling tube 103. At the same time, the rotation of the sampling tube 103 causes the soil sample to be squeezed by the swing bar 204, thereby further improving the breaking up of the soil sample. The movement of the movable sleeve 205 can be limited to the maximum movement distance through the sliding cooperation between the limiting strip 209h and the limiting groove 209g, preventing the movable sleeve 205 from falling off.

[0055] When it is necessary to discharge and collect the broken soil sample, first turn off the motor 105c to stop the sampling cylinder 103 from rotating. Then, the user can take the collection box and move it to the bottom of the sampling cylinder 103 and remove the installed cover. Then, turn on the motor 105c again so that the motor 105c drives the sampling cylinder 103 to rotate and discharge the loose soil sample. At the same time, the sliding of the guide block 206 inside the threaded guide groove 208 can also discharge the residual soil sample on the inner wall.

[0056] As the movable sleeve 205 reciprocates, it drives the first piston rod 209a to reciprocate inside the swing crossbar 204, thereby continuously pushing the gas through the first connecting valve 209b, the second connecting valve 209c, and the ventilation groove 209d to be discharged and blown onto the soil sample surface. The airflow pushed out can further loosen the broken soil sample, thereby improving the breaking effect of the soil sample. When the broken soil sample is discharged, the airflow can also further loosen the residual soil sample on the inner wall of the sampling cylinder 103, thereby cleaning the inner wall of the sampling cylinder 103. At the same time, the filter pad 209e can prevent soil fragments from entering during gas extraction, and can prevent the filter pad 209e from clogging during air jetting.

[0057] After the soil sample is prepared, the user activates the electric telescopic rod 201, which moves the mounting plate 102 upward to reset. This causes the mounting plate 102 to move the second piston rod 301b upward, squeezing the water in the piston cylinder 301a upward and discharging it through the one-way outlet valve 301i into the mounting pipe 301d. The mounting plate 102 also moves the insertion rod 203 and the swing crossbar 204 upward, causing the swing crossbar 204 to approach the double inclined block 301g, thus gradually contacting the double inclined block. When the face block 301g contacts the wall, the pressing valve 302a moves within the movable groove 301c to avoid being affected by the mounting plate 102. Then, the double-sloped face block 301g is pushed outwards by the pushing force, pressing the inside of the pressing valve 302a, causing the pressing valve 302a to open. At this time, the water spray ring 301e communicates with the mounting pipe 301d through the pressing valve 302a, and then the opened water spray ring 301e opens and sprays water onto the insertion rod 203 and the swing crossbar 204. The cleaning process is achieved by opening the corresponding water spray ring 301e and spraying water only when the corresponding double inclined block 301g moves outward, thus achieving a layer-by-layer opening effect. When the second piston rod 301b moves upward and the other water spray rings 301e are not opened, the excessive pressure in the piston cylinder 301a will open the pressure relief valve 301f, allowing the excess pressure to carry excess water back to the external water source for recycling. This avoids the phenomenon of water waste caused by opening all the water spray rings 301e at the beginning of the movement of the insertion rod 203, resulting in a large number of water spray rings 301e not yet corresponding to the insertion rod 203 and the swing crossbar 204 for cleaning. In addition, the sprayed water will also flow into the sampling cylinder 103 to clean the sampling cylinder 103. When the electric telescopic rod 201 drives the insertion rod 203 to move downward, it will simultaneously drive the second piston rod 301b to generate a suction force in the piston cylinder 301a, thereby drawing water from the external water source into the piston cylinder 301a through the one-way water inlet valve 301h for standby.

[0058] In summary, firstly, the sampling mechanism 100 is activated to drill into the soil and take soil samples. Then, the discharge mechanism 200 is activated to break up and discharge the sampled soil. This breaking up not only facilitates subsequent testing but also makes it easier to remove the soil. Finally, the cleaning mechanism 300 is activated to clean the sampling mechanism 100 and the discharge mechanism 200.
